The variable tank outlet or fluid intake a consists of a head or main body 1, provided atone end with a packing gland 2 which is of the usual construction and comprises a nut 3 threaded onto the body 1,. and adaptedto force the packing about the rod or tube 7 extending therethrouglm; The body 1 is provided at the end opposite the gland 2 with'a threaded sections: which is adapted to be threaded into the usual nut 5 welded onto'the fuel tank 5, eith'er on the top or the bottom thereof, as will -be further described. A sleeve 6 extends beyondand from the threaded section 4, the purpose of which-will be further amplified.

A tube 7 extends through, and-is slidable in, a longitudinal bore 8 extending through the body 1 and sleeve 6. This tube extends into the tank 5 and is open on the end within the tank, but theopposite endisclosed and a handle 9 is secured thereto. A pair of spaced holes 10. and 11 arranged one above theother' extend through the tube 7 from the bore of the tube, and are adapted to be selectively brought into alinement with an outlet duct 13. This duct extends through a boss lawhich'is formed onthe body 1 adjacent the section 4, andthe boss is providedwith a threaded extension upon which a 11111315 is threaded to hold the outlet pipe 1'6 in'alinement with the duct. 1 i A stop ring 17 is formed or secured on the tube 7, and is adaptedto limit the upward movement of said I tube by engaging the sleeve 6. The'ring is so spaced on the. tube that'when it engages the sleeve 6 the hole will be in alinement with the outlet duct 13; The handle 9 is also spacedabove the top of the body 1, 'i.,e abovelthe gland 2; a distance equal to the space between the two holes 10 and 11. Thus it willbe seen that with thehandle 9raised above the-body 1 and the .ring 17 engaging the sleeve 6 the hole 10-registers with the duct 13, and'the fluid isidrawn by the usual vacuum'means, not shown, through the tube7, hole 1O, duct 3 13 into the outlet'pipe 16 and may be withdrawn from the tank until the 'level of the fluid reaches the heightv predetermined by the distance the end of the tube '7 is inserted into the tank. When the handle 9 is moved downwardly until it engages the top of the body 1 thehole 11 registers with the duct 13' to permit the tank to be practically en- 7 tirely emptied offiuid.

InrFigs. 1 to 3 inclusive the body is threaded into the top of the tank 5 and the tube 7 extendsdownwardly into the fluid.

. This construction is applicable for use in connection with a pump, vacuumtank, etc. The tube 7 is ofsucha length that with thehandle; 9 in the raised L'position the bottom ofsaid tubedoes notjextend to the e This surplus supply may be drawn upon.

by the operator or attendant moving the handle 9 and consequently the tube 7 downwardly as shown in dotted lines in Fig. 2,

this immerses the end of said tube in the remaining liquid. The outlet of the fuel is then through the tube 7 and hole 11as previously described. In construction which the fluid is drawn by gravity.

shown in Fig. 9 we have" shown our inventlon applied to a tank from In such construction the body 1 threads I into the bottom "of the tank 5 and the tube 7 extends upwardly into the fluid. When i the handle 9 is against the bottom of the body l the end of the tube 7 is above the bottom. of the tank, thus providingan emergency supply. Bylower-ing the tube 7 c and handle 9, as shown in dotted lines Fig. 9, the end ofthe tube is. brought to b the bottom of the tank and the tank may then be completely emptied. we 2 The sleeve 6 in Figs. 1-8 serves to cover 'the hole 10 in the lowered position of the tube 7 so that the fluid. must be drawn through the bottom of the tube. By rotating the handle 9 thus moving the holes 10 or 11 out of registry with the outlet, the fluid supply may be stopped. An arrow 18 on the handle 9 as shown in Fig. 1, indicates the open position. I To prevent the accidental displacement of the tube 7 from theraisedto' the lowered position when applied to the top of a tank we provide a clip 19, which encircles the r.

tube 7 between the handle 9 and the'top of the body 1. This clip may have a pair of lugs 20 thereon through which bolt 21 extends to securely fix the same on. the tube 7 or such clip maybe as shown inv Fig.8.

This clip must lac-removed before the tube 7.,may be moved. In Fig. 9 we have shown a set screw 22 extendingthrough the body 1 against the tube 7 thus holding. said tube in position. 1 j g In the modified form shown in Figspltl and'll a type of outlet or intake extendingv through the bottom of the tank 5 is shown.

A'tube 25 extends through a hollow'fnut 2 6 threaded' into the tank 5 andthrough a packing gland 27 on the bottom of said nut.

A ring 28 on the upper end of the tube 25. is adapted to engage the nut 26 to limit the downward movement of the tube. The

lower "end of thetube 25 is enlarged as at.

29, andinternally threaded to receive a valve 30 from which valve a flexible pipe 31 ex tends- This construction is very inexpena sive', and easy to install.

Regulation of the supply is accomplished I moving thefltube 25,:and valve up slightly modified forms ofthe type of'tank wardly or downwardly,the pipe 31 bending I sutficiently to accomplish this. The glandy 27 is drawn tight enough toprevent acc.i-,

dental displacement of the tube 25.]

In Figs. 12 to '18 inclusive we have shown outletextending into the'ltop of the tank.

The construction in. said figures is identical in so far 'asthe body 1, g1and2, section 4, tube 7,"ring 1-7 are concerned. The body 1 in Figs. 12 andlS is provided with a nut section spaced from the threads l.

.An annular ring Blis positioned between the nut sectionBO and the top of thetank .5 and is spaced slightly from'said body providingan annular space 32'. 'The ring 31f is formed Witha threaded outlet boss 33"on which the nut 34 is threaded holding the outlet pipe'35 in'position thereon. The ring angle 7 Slots 36 are formed int-he tube 7 through- I out the length of travel of said tube, and

these communicate with ports 37in the body 1, which ports extend tothe space 32 thus "providing an outlet for the fluid. If desired the tube 7 maybe perforated as shown :11338 in Fig. 17. l i

' lnFigs l to 16and 18jjii1clusiveslightly nodifiedforlns of outlets are shown. These H outlets "are arrangedso that no stoppage will occur if the tube 7 should-be rotated.
